Titre de l’invention : Charnière pantographe comprenant un dispositif de recentrage Domaine technique auquel se rapporte l'inventionTitle of the invention: Pantograph hinge comprising a recentering device Technical field to which the invention relates
[0001] La présente invention revendique la priorité de la demande française 2103103 déposée le 26 Mars 2021 dont le contenu (texte, dessins et revendications) est ici incorporé par référence. The present invention claims the priority of French application 2103103 filed on March 26, 2021, the content of which (text, drawings and claims) is incorporated herein by reference.
[0002] La présente invention concerne le domaine technique des véhicules automobiles et, plus particulièrement, les charnières pantographes employées pour manœuvrer un ouvrant d’un véhicule automobile. The present invention relates to the technical field of motor vehicles and, more particularly, the pantograph hinges used to maneuver an opening of a motor vehicle.
Arrière-plan technologique Technology background
[0003] Dans le domaine de l’automobile, il est connu l’emploi de charnières pantographes pour manœuvrer un ouvrant d’un véhicule automobile. De façon avantageuse, les charnières pantographes permettent des lignes de découpes plus imbriquées entre l’ouvrant et la carrosserie, lorsque l’ouvrant est fermé. Les charnières pantographes sont ainsi de plus en plus utilisées pour créer de nouvelles esthétiques. [0003] In the automotive field, the use of pantograph hinges is known to operate a door of a motor vehicle. Advantageously, the pantograph hinges allow more overlapping cut lines between the leaf and the bodywork, when the leaf is closed. Pantograph hinges are thus increasingly used to create new aesthetics.
[0004] Les charnières pantographes sont des charnières plus complexes que les charnières ciseaux ou les charnières cols de cygne, habituellement utilisées dans ce domaine. Une charnière pantographe se compose d’un charnon fixe, destiné à être solidarisé à la carrosserie d’un véhicule automobile, et d’un charnon mobile destiné à maintenir un ouvrant. Les charnons fixe et mobile sont reliés par l’intermédiaire de biellettes. Chaque extrémité des biellettes est maintenue à un charnon par l’intermédiaire d’une liaison pivot, dont l’axe de rotation est perpendiculaire à l’axe longitudinal de la biellette. Les biellettes permettent ainsi un mouvement d’écartement ou de rapprochement des charnons, selon une trajectoire non circulaire. [0004] Pantograph hinges are more complex hinges than scissor hinges or gooseneck hinges, usually used in this field. A pantograph hinge consists of a fixed knuckle, intended to be secured to the bodywork of a motor vehicle, and a mobile knuckle intended to hold an opening. The fixed and mobile knuckles are connected by connecting rods. Each end of the rods is held to a knuckle by means of a pivot link, the axis of rotation of which is perpendicular to the longitudinal axis of the rod. The rods thus allow a movement of spacing or bringing together of the knuckles, according to a non-circular trajectory.
[0005] Du fait du nombre de pièces et de la complexité de leur articulation, les charnières pantographes sont plus flexibles que les charnières habituellement utilisées dans le domaine de l’automobile. Afin de renforcer leur rigidité, il s’avère nécessaire de mettre sous contrainte mécanique les charnières pantographes lorsqu’elles sont fermées. [0005] Due to the number of parts and the complexity of their articulation, pantograph hinges are more flexible than conventional hinges. used in the automotive industry. In order to reinforce their rigidity, it is necessary to place the pantograph hinges under mechanical stress when they are closed.
[0006] Cette mise sous contrainte est réalisée à l’aide d’une butée mécanique, liée au charnon fixe, dont l’extrémité libre est de surface plane et destinée à prendre appui contre un rebord plan d’une biellette. En dépit de cette mise sous contrainte mécanique, il a été constaté l’existence d’un jeu de glissement latéral entre les charnons, lorsque la charnière pantographe est fermée. This stressing is carried out using a mechanical stop, linked to the fixed knuckle, the free end of which has a flat surface and is intended to rest against a flat edge of a rod. Despite this mechanical stressing, it was observed that there was a lateral sliding clearance between the knuckles when the pantograph hinge was closed.
[0007] L’invention vise à réduire ce jeu de glissement latéral, en proposant une charnière pantographe comprenant un dispositif de centrage dédié. [0007] The invention aims to reduce this lateral sliding play, by proposing a pantograph hinge comprising a dedicated centering device.
Objet de l’invention Object of the invention
[0008] Pour cela, l’invention propose une charnière pantographe comprenant : For this, the invention proposes a pantograph hinge comprising:
[0009] - un charnon fixe, destiné à être solidarisé à la carrosserie d’un véhicule automobile ; et [0009] - a fixed knuckle, intended to be secured to the body of a motor vehicle; and
[0010] - un charnon mobile, destiné à maintenir un ouvrant ; et [0010] - a movable knuckle, intended to maintain an opening; and
[0011] - deux biellettes dont les extrémités sont maintenues aux charnons par l’intermédiaire de liaisons pivots, les axes de rotation des liaisons pivots étant parallèles à un même axe de travail, une des biellettes comprend un rebord s’étendant dans une direction parallèle ou sensiblement parallèle à l’axe de travail ; et - two rods whose ends are held to the knuckles by means of pivot links, the axes of rotation of the pivot links being parallel to the same working axis, one of the rods comprises a flange extending in a parallel direction or substantially parallel to the working axis; and

[0012] - the fixed knuckle comprises a mechanical stop arranged so as to bear against the edge of the rod, when the pantograph hinge is closed.
[0013] L’invention est remarquable en ce que la butée mécanique et le rebord de la biellette sont de forme complémentaire, de manière à s’emboîter selon une direction radiale ou sensiblement radiale à l’axe de travail, lorsque la charnière pantographe est refermée. The invention is remarkable in that the mechanical stop and the edge of the rod are of complementary shape, so as to fit together in a direction radial or substantially radial to the working axis, when the pantograph hinge is closed.
[0014] L’emboîtement de la butée mécanique et du rebord de la biellette permet avantageusement de former une nouvelle liaison mécanique, entre le charnon fixe et la biellette. Ainsi, la rigidité mécanique de la charnière pantographe est accrue lors de sa fermeture. Le phénomène de glissement entre les charnons est de ce fait réduit lorsque la charnière pantographe est fermée. [0015] L’invention porte également sur les variantes de réalisation suivantes : [0014] The interlocking of the mechanical stop and the edge of the connecting rod advantageously makes it possible to form a new mechanical connection between the fixed knuckle and the connecting rod.

[0024]- the mechanical stop is screwed into the fixed knuckle, and the screwing axis of the mechanical stop is perpendicular to an axis passing through the pivot connections of the connecting rod comprising the flange, when the mechanical stop and the flange are nested .

Description détaillée de l’invention Detailed description of the invention
[0034] Pour rappel, l’invention propose une charnière pantographe, permettant de réduire un phénomène de glissement latéral entre les charnons de la charnière, en position fermée. As a reminder, the invention proposes a pantograph hinge, making it possible to reduce a lateral sliding phenomenon between the knuckles of the hinge, in the closed position.
[0035] Les figures 1 à 4 représentent un mode de réalisation non limitatif d’une charnière pantographe 2 selon l’invention. Figures 1 to 4 show a non-limiting embodiment of a pantograph hinge 2 according to the invention.
[0036] La charnière pantographe 2 comprend un charnon fixe 4 et un charnon mobile 6. Le charnon fixe est destiné à être fixé à la carrosserie d’un véhicule automobile non représenté. Le charnon mobile est destiné à être fixé sur un ouvrant non représenté. Les charnons sont liés entre eux par l’intermédiaire de deux biellettes 8, 8A. Les extrémités des biellettes sont maintenues aux charnons par l’intermédiaire de liaisons pivots 10. Les liaisons pivots 10 permettent le pivotement des biellettes autour d’axes de rotation, parallèles ou sensiblement parallèles à un axe de travail 12 visible sur la figure 2. The pantograph hinge 2 comprises a fixed knuckle 4 and a mobile knuckle 6. The fixed knuckle is intended to be fixed to the bodywork of a motor vehicle, not shown. The movable knuckle is intended to be fixed on an opening not shown. The knuckles are interconnected via two rods 8, 8A. The ends of the rods are held to the knuckles by means of pivot connections 10. The pivot connections 10 allow the pivoting of the rods around axes of rotation, parallel or substantially parallel to a working axis 12 visible in figure 2.
[0037] Le charnon fixe 4 comporte un bord 14 faisant saillie. Le bord 14 s’étend selon une direction parallèle ou sensiblement parallèle à l’axe de travail 12. Une ouverture est ménagée à travers le bord 14, de sorte à permettre le passage d’une butée mécanique 16. Selon le présent exemple, la butée mécanique comprend une tige filetée et la paroi interne de l’ouverture est taraudée afin de contrôler précisément la longueur de l’extrémité libre de la tige filetée dépassant du bord 14. Selon le présent exemple, le sommet 18 de la butée mécanique est de forme convexe, plus précisément de forme conique. [0038] Un rebord 20 d’une biellette 8A s’étend également selon une direction parallèle ou sensiblement parallèle à l’axe de travail 12. Le rebord est agencé sur la biellette de sorte à être en vis-à-vis de la butée mécanique 16. Comme illustré par les figures 3 et 4, le rebord 20 comporte un renfoncement 22 configuré pour permettre l’emboîtement du sommet 18 de la butée mécanique, lorsque la charnière pantographe est fermée (voir figures 3 et 4). The fixed knuckle 4 has an edge 14 projecting. The edge 14 extends in a direction parallel or substantially parallel to the working axis 12. An opening is provided through the edge 14, so as to allow the passage of a mechanical stop 16. According to the present example, the mechanical stop comprises a threaded rod and the internal wall of the opening is tapped in order to precisely control the length of the free end of the threaded rod protruding from the edge 14. According to the present example, the top 18 of the mechanical stop is of convex shape , more precisely of conical shape. A flange 20 of a link 8A also extends in a direction parallel or substantially parallel to the working axis 12. The flange is arranged on the link so as to be vis-à-vis the stop mechanical 16. As illustrated by Figures 3 and 4, the flange 20 has a recess 22 configured to allow the engagement of the top 18 of the mechanical stop, when the pantograph hinge is closed (see Figures 3 and 4).
[0039] Ainsi, lorsque la charnière pantographe 2 est refermée, une nouvelle liaison mécanique est formée entre le charnon fixe et la bielle 8A, par l’imbrication du sommet 18 de la butée mécanique dans le renfoncement 22 du rebord 20. La rigidité mécanique de la charnière pantographe est de ce fait accrue, et le phénomène de glissement latéral entre les charnons est minimisé. En d’autres termes, la butée mécanique 16 et le rebord 20 de la biellette 8A forme un dispositif de recentrage lors de la fermeture de la charnière pantographe 2. Thus, when the pantograph hinge 2 is closed, a new mechanical connection is formed between the fixed knuckle and the connecting rod 8A, by the nesting of the top 18 of the mechanical stop in the recess 22 of the rim 20. The mechanical rigidity of the pantograph hinge is therefore increased, and the phenomenon of lateral sliding between the knuckles is minimized. In other words, the mechanical stop 16 and the rim 20 of the connecting rod 8A form a recentering device when the pantograph hinge 2 closes.
[0040] De préférence, la paroi interne de l’ouverture s’étend le long d’un axe 24 formant un angle, avec un axe 26 passant par les centres des liaisons pivots 10, dont la valeur est de l’ordre de 90, de préférence égale à 90°. Preferably, the internal wall of the opening extends along an axis 24 forming an angle, with an axis 26 passing through the centers of the pivot links 10, the value of which is of the order of 90 , preferably equal to 90°.
[0041] La figure 5 illustre une variante de réalisation de l’invention, se distinguant du mode de réalisation décrit ci-dessus, en ce que le rebord 20 de la biellette n’est pas renfoncé. Le rebord 20 sert de support à un ergot 28, maintenu en vis- à-vis de la butée mécanique 16. L’ergot comprend un renfoncement au niveau de son sommet 30, dont la forme complémentaire au sommet 18 de la butée mécanique, de sorte à permettre l’emboîtement dudit sommet lorsque la charnière pantographe 2 est fermée. Figure 5 illustrates an alternative embodiment of the invention, differing from the embodiment described above, in that the flange 20 of the rod is not recessed. The flange 20 serves as a support for a lug 28, held vis-à-vis the mechanical stop 16. The lug comprises a recess at its top 30, the shape of which complements the top 18 of the mechanical stop, so as to allow the interlocking of said top when the pantograph hinge 2 is closed.
[0042] La figure 6 illustre une variante de réalisation de l’invention, se distinguant du mode de réalisation décrit ci-dessus, en ce que l’ergot 28 maintenu en vis- à-vis de la butée mécanique 16, comprend une excroissance 32 de forme complémentaire à un renfoncement 34 ménagé au sommet de la butée mécanique 16. [0043] Bien entendu, l’invention ne se limite pas à ces seuls modes de réalisation, de sorte que l’emboitement de la butée mécanique avec le rebord de la biellette peut être réalisé d’autres manières [0042] Figure 6 illustrates an alternative embodiment of the invention, differing from the embodiment described above, in that the lug 28 held vis-à-vis the mechanical stop 16, comprises a protrusion 32 of complementary shape to a recess 34 formed at the top of the mechanical stop 16. Of course, the invention is not limited to these embodiments alone, so that the interlocking of the mechanical stop with the edge of the connecting rod can be achieved in other ways.
